The application relates to mixtures of binders or adhesives which can be employed for the manufacture of plywood and timber materials with compounds of general formula (I) in which R represents hydrogen, optionally substituted radicals of the group consisting of acyl, alkyl, aryl, aralkyl, heteroaryl and heteroarylalkyl; A represents a monofunctional group from the series hydrogen, acyl, alkyl, aryl, or represents a bifunctional group which is linked to the radical Z; E represents an electron-withdrawal radical; X represents the radicals -CH= or =N-, it being possible for the radical -CH= to be linked to the radical Z instead of an H atom; Z represents a monofunctional group from the series alkyl, -O-R, -S-R, (a) or represents a bifunctional group which is linked to the radical A or the radical X; the compound Imidocloprid being particularly preferred.
